From the free energy surfaces in G-p-T space a series of basic characteristics have beensummarized. For the reactions of most systems with phases of constant c
Five species of Asterometrids (Crinoidea) collected from China are recorded. One of them is described as a new genus and new species named Sinometra acuticirra
Until now most of the nonlinear wave theories are confined to expound the nonlinear properties relative to a stationary wave train and inclusive of three dimen
Aryllithium reacts with Cp_2MCl_2 and Cp’_2 MCl_2 (C_p=η~5-C_5H_5, C_P′=η~5-CH_3C_5H_4:M=Ti, Zr, Hf) respectively to prepare a series of new bis (cyclopent
In this paper some new hypotheses corresponding to cleft mechanisms and peak-heightcquation of mass spectra for conjugated organic compounds are proposed on th
